High space heating in winter has always been a problem in the industry. In the space of tall buildings, there are widespread problems such as large heating area, poor wall insulation capacity and high energy consumption. At present, the heating of tall space mainly uses radiation heating and convection heating. So the two ways of comparison, which is more suitable for tall space heating?

The traditional heating method of tall space buildings, such as industrial plants, is to use heat sources such as hot water boilers, steam boilers through pipelines and air handling units, heaters, radiators and other cooling equipment to heat the air in the plant, relying on air convection to achieve heating purposes. However, in the traditional convective heating system, due to the rise of hot air, a large amount of heat is consumed in the upper part of the tall building, and the lower working area is difficult to obtain enough heat, and the temperature distribution is uneven, which not only causes energy waste, but also poor thermal comfort. 
 
The heat in the radiation heating process is mainly concentrated in the middle and lower part of the room, which is more conducive to being absorbed and utilized by the human body, the temperature rise is faster, the thermal comfort is strong, the energy consumed in the air is less, the energy utilization rate is high, and the heating effect is good. Therefore, radiation heating can better reduce the influence of temperature gradient than the previous two traditional heating methods. 
 
When the indoor air temperature is the same, radiant heat directly transfers heat to the heating object. The realistic temperature of radiant heating is 2~3℃ higher than that of convective heating. That is to say, under the condition that the indoor realistic temperature is the same, the indoor air temperature of radiant heating is 2~3℃ lower than that of heating, so the indoor heat consumption is small and the temperature difference between indoor and outdoor is small. The cold air permeability is also small, thus improving the indoor heating effect. 
 
The experiments show that the room temperature of 16℃ under the radiant heat condition is equivalent to the convection environment of 18~20℃. It is understood that if the room temperature is reduced by 1 ° C, about 10% of energy can be saved. 
 

	In recent years, infrared radiation heating methods (gas radiation heating system, hot water radiation panel, etc.) have been implemented and widely used, which is suitable for the comprehensive heating of tall space buildings and local area or local work place heating. Therefore, the use of advanced infrared heating equipment, industrial enterprises not only achieve energy saving and emission reduction, but also create a comfortable working environment for employees, create more considerable economic benefits, to maximize economic benefits.
